"communication information" is a general concept that represents both meaning content (information) and physical expression (signal). Even if the meaning of a communication is the same-i.e., the same information-different signal forms may occur. So that a communication relating to an object may for example be

(1) In the form of a picture or a picture,

(2) as a statement of a word or phrase that is spoken,

(3) as a sentence in writing, the user can write,

(4) transmitted as encoded sentences or pictures. The transmission according to (1) … (3) is generally characterized by a continuous (analog) signal, whereas discontinuous signals (e.g., pulses, digital signals) are usually generated in the transmission according to (4).

Starting from this general definition of the communication system, the invention relates according to the preamble of claim 1 to a method for controlling the set-up of transmission lines (bearers) in Radio Local Loop/wireless Local Loop systems in wireless telecommunication systems, in particular DECT-specific RLL/WLL systems (Radio Local Loop/wireless Local Loop) incorporated as Local communication information transmission loops in ISDN systems.

The DECT/ISDN intermediate system DIIS or RLL/WLL telecommunications local system RW-TTS is here especially a digital enhanced (formerly: European) cordless telecommunications built on a DECT/GAP system DGS; please compare (1): communications technology electronics 42(1992) 1/2 month 1 Berlin, Germany; the structure of the DECT standard, written by pilger, 23 th to 29 th in conjunction with ETSI european telecommunications standards institute publication ETS300175-1 … 9, month 10 1992; (2): telecommunication reports 16(1993), 1 st, by j.h. koch: the digital comfort of cordless telecommunications-DECT standard opens up a new field of use ", pages 26 to 27; (3): tec 2/93-Ascom, journal of technology, pages 35 to 42, road to universal mobile telecommunications; (4) philips telecommunications review volume 49, 3 rd, 9 months 1997, authored by r.j.mulder: "DECT, a universal cordless access system": (5): WO93/21719 (FIGS. 1 to 3 and the accompanying description) ]. The GAP standard (generic access profile) is a next office part of the DECT standard, and is based on the task of ensuring interoperability of DECT air interfaces for telephone use (see ETSI publication rpETS 300444, month 4 1994).

The DECT/ISDN intermediate system DIIS or the RLL/WLL telecommunications local system RW-TTS can alternatively also be based on a GSM system (private mobile telecommunications group or global system for mobile communications; please compare informatics, journal of 14(1991) 6.6.3 rd, Berlin, DE; A.Mann: "GSM Standard-base for digital European Mobile radio networks", pages 137 to 152). In addition, it is also possible to design the ISDN telecommunication local system I-TTS as a GSM system within the scope of a hybrid telecommunication system.

In addition, the systems mentioned at the outset and also systems in the future can be considered as further possibilities for implementing the DECT/ISDN intermediate system DIIS or the RLL/WLL telecommunications local system RW-TTS or the ISDN telecommunications local system I-TTS on the basis of the known multiple access methods FDMA, TDMA, CDMA (frequency division multiple access, time division multiple access, code division multiple access) and the hybrid multiple access methods formed therefrom.

The use of radio communications (e.g. DECT channels) in conventional wired telecommunications systems, like ISDN, is becoming increasingly important, especially in the context of future alternative network operators who do not have their own complete wire network.

Thus, for example, in the case of an RLL/WLL telecommunications local system RW-TS, for example in the case of a DECT system DS, the radio connection technology RLL/WLL radio local loop/cordless local loop) should be such that the various ISDN services on the standard ISDN interfaces are available to the ISDN subscribers (see fig. 1).

In the ISDN ← → RLL/WLL "telecommunication system IDRW-TS specific for DECT, according to fig. 1, a telecommunications subscriber (user) TCU with its terminal equipment TE (terminal end; terminal equipment) is accommodated in the ISDN world with its services available therein, for example via a standardized S interface (S bus), via a standardized U interface which is formed as a local communication information transmission loop, in particular dedicated for DECT and a-DECT/ISDN intermediate system DIIS (first telecommunication local system) which is included in the RLL/WLL telecommunication local system RW-TTS, via a further standardized S interface (S bus), a network terminal NT and a standardized U interface of the ISDN telecommunication local system I-TTS (second telecommunication local system).

The first telecommunications local system DIIS essentially comprises two telecommunications interfaces, a first telecommunications interface DIFS (DECT intermediate fixed system) and a second telecommunications interface DIPS (DECT intermediate portable system), which are connected to one another wirelessly, for example via a DECT air interface. Due to this quasi-stationary first telecommunications interface DIFS, the first telecommunications local system DIIS forms a local communication information transmission loop as defined above in this connection. The first telecommunications interface DIFS comprises a radio fixed part RFP, an adaptation unit IWUI (interworking unit) and an interface circuit INC1 to the S interface. The second telecommunications interface DIPS comprises a radio mobile part RPP and an adapter unit IWU2 and an interface circuit INC2 to the S interface. The radio fixed part RFP and the radio mobile part RPP form here the known DECT/GAP system DGS.

The following general problems exist for a DECT-specific RLL system with as much as possible of the entire ISDN service in the subscriber connection as a bearer.

a) Duplicating the ISDN information structure (D channel and 2B channels), in the following especially D

The duplication of the channel is carried out,

b) good bandwidth economy; is especially important for ISDN, since for 64kbps

Several services already require two DECTs for a B-channel data rate of (kilobits/second)

The channel(s) are (are) transmitted,

c) with minimal technical expenditure.

Duplication of D channels

Performance of D channel:

a common signalling channel on the C-plane for all terminal equipments TE connected on the ISDN connection.

In which the TE-specific signalling channels to the network are separated by means of a TE-unique address TEI (terminal end identifier).

The access mechanism to the D channel ensures a TE unique order of the communicated information.

-passage rate: 16 kbit/s

-full load rate: depending on a number of criteria, typically below maximum capacity; various blocking situations are possible, however they can be quickly ruled out due to the high capacity.

DECT channel:

according to literature communications technology electronics 42(1992) month 1/month 2, stage 1, Berlin, DE; pilger, U.S.: "architecture of the DECT Standard", pages 23 to 29, in conjunction with ETS300175-1 … 9, month 10 1992 ", FIG. 2 shows the TDMA architecture of the DGS of the DECT/GAP system. The DECT/GAP system is a hybrid system for multiple access methods, on which radio communication information can be transmitted from the base station RFP to the mobile part RPP and from the mobile part RPP to the base station RFP (duplex operation) in a given time sequence according to the TDMA principle on ten frequencies in the frequency band between 1.88 and 1.90GHZ according to the DECT/GAP system. The time sequence is determined by a multi-time frame MZR which occurs every 160ms and has 16 time frames ZR each having a duration of 10 ms. In these time frames ZR, information is transmitted to the base station RFP and the mobile part RPP, respectively, which relate to a C-, M-, N-, P-, Q channel defined in the DECT standard. If information is transmitted for several of these channels in a time frame ZR, the transmission is carried out according to a priority list with M > C > N and P > N. Each of the 16 time frames ZR of the multi-time frame MZR is subdivided into 24 time slots ZS each having a duration of 417 μ s, from which 12 time slots ZS (time slot 0 … 11) are designated as transmission direction, base station RFP → mobile part RPP ", and the other 12 time slots ZS (time slot 12 … 23) are designated as transmission direction, mobile part RPP → base station RFP". In each of these time slots ZS, information having a bit length of 480 bits is transmitted in accordance with the DECT standard. From this 480 bits, 32 bits are transmitted as synchronization information in a SYNC field, and 388 bits are transmitted as useful information in a D field, the remaining 60 bits are transmitted as additional information in a Z field and guard information in a "guard time" field. For useful information transfer, the 388 bits of the D field are subdivided into a 64 bit long A field, a 320 bit long B field and a 4 bit long, X-CRC "word. The 64-bit long a field is composed of an 8-bit long Header (Header), a 40-bit long data item with information data for C-, Q-, M-, N-, P, and a 16-bit long, a-CRC "word.

Performance:

-using TDMA time slots.

In principle, one Cs message (S ═ slow) is used in each time slot for signaling [ C Plane (C-Plane) in the DECT standard ] and a subordinate channel [ U Plane (U-Plane) in the DECT standard ] for user information or useful information (throughput: 32 kbits/sec).

-C_sThroughput rate of channel: 2 kbit/s.

The DECT standard also provides for additional channel structures, e.g. a C_fChannel (f ═ fast).

-the C_fThe channel occupies one time slot.

-C_fThroughput rate of channel: 25.6 kbit/s.

Bandwidth economy

C_sThe channel structure provides an optimum bandwidth economy for a standard voice connection, since according to fig. 5 from fig. 3 and fig. 4, and considering the ETSI publications (ETS300175-1, 10/1992, chapter 7; ETS300175-3, 10/1992, chapter 4.1; ETS300175-4, 10/1992, chapter 4) only one transmission line (bearer) -e.g. an MBC with LCNy, LCN1 according to fig. 5-or only one connection or one time slot is needed.

According to FIG. 5 from FIGS. 3 and 4, and considering the ETSI publications (ETS300175-1, 10)1992, Chapter 7; ETS300175-3, 10/1992, chapter 4.1; ETS300175-4, 10/1992, chapter 4), C)_fThe use of channels leads to a lower bandwidth economy, since the U-Plane (U-Plane) itself requires a further transmission line (carrier), specifically a further connection or a further time slot; this means that two transmission lines (carriers) are necessary — for example, an MBC with LCN2, LCNz and an MBC with LDNy, LCN1 according to fig. 5 — specifically two connections or two time slots for simple voice connections.

In addition, for the case where two ISDN-B channel connections (voice connections) are present, three transmission lines (bearers), for example an MBC with LCNx, LCNo according to fig. 5, an MBC with LCNy, LCN1 and an MBC with LCNz, LCN2, are necessary, to be precise three connections or three time slots.

Using C from a bandwidth economy perspective_sThe channel is rational, and C is adopted from the viewpoint of channel capacity_fThe channel appears to be legitimate.

The object on which the invention is based is to optimize the set-up and use of transmission lines in the number of transmission lines for the transmission of radio communication information in radio telecommunication systems, in particular in DECT-specific RLL/WLL systems which are integrated as local communication information transmission loops in ISDN systems.

This object is solved according to the method defined in the preamble of claim 1 by the features specified in the characterizing part of claim 1.

The idea on which the invention is based consists in controlling the establishment and the application of the individual transmission lines between the radio transmission means/radio reception means in the respective radio telecommunication systems described at the outset and in the general manner by the transmission line numbers being transmitted onto the individual transmission lines in such a way that collisions in the establishment and the use of the individual transmission lines (the connections) are avoided and at the same time the resources of the air interface are effectively utilized. This reduces the effort and the error-prone connection set-up (setting up of the transmission lines) in the individual telecommunication systems.

This is achieved by controlling the transmission line numbers as follows. Method for controlling the set-up and utilization of transmission lines (bearers) in wireless telecommunication systems, in particular DECT-specific RLL/WLL systems incorporated as local information transmission loops in ISDN-systems, in which method

a) Establishing an intermediate first radio transmission device/device in a telecommunications system (DIFS)

Radio receiver (DIFS) and a second radio transmitter/radio

These transmission lines between the receiving Devices (DIPS),

b) transmitting line number (LCNx, LCNy, LCNz, LCN0, LCN1, LCN2)

To be distributed to these transmission lines,

c) on these transmission lines, individual transmission channels with individual transmission capacities dedicated to the channels

Road (C)_s，C_f) To transmit system-specific system communication information,

it is characterized in that the preparation method is characterized in that,

d) the radio transmitting device/radio receiving device (DIFS, DIPS) are in one

First transmission channel (C) with a first channel-specific transmission capacity_f) In, e.g.

A first transmission line for transmitting system communication information is established in such a way that

A first transmission line number (LCNx, LCN0) is assigned to the first transmission line

The first transmission line number (LCNx, LCN0) is not yet allocated to other transmission lines

And (4) routing.

It is advantageous if, for the transmission of system traffic, a collision-free transmission line number of a transmission line is reserved in a transmission channel with channel-specific transmission capacity.

Advantageously, the channel switching can be controlled by the control of the transmission line numbers described.

It is further advantageous if the described control signals a desire of a radio transmitter/radio receiver to switch channels to a further radio transmitter/radio receiver.

Further advantageous further developments of the invention are specified in the remaining dependent claims.

A first embodiment of the present invention is described with reference to fig. 6 and 7.

FIG. 6 shows an incentive status chart of how the number of the transmission line can be controlled to achieve the goal of C with the least cost of the transmission line (saving air interface resources)_fDirection of production stop C_sChannel switching of the channel.

The first telecommunications interface DIFS (radio transmitting/radio receiving) is a first transmission channel C on a first transmission line with a first transmission line number LCNx (logical connection number; reference number)_fConnected to a second telecommunications interface DIPS (radio transmitting/radio receiving device). The first telecommunications interface DIFS requests the U-plane on the second telecommunications interface DIPS with a first NWK signal "CC-SETUP" (compare ETSI publication ETS300175-5, chapter 6.3.2.1, 10.1992) and with a first transmission line number LCNx.

This acknowledgement is placed from the DECT-B field into the DECT-a field by a first MAC signal, flag _ T. _ REQUEST (ATTRIBUTES _ T. _ REQUEST) and a second MAC signal, flag _ T. _ acknowledgement (ATTRIBUTES _ T. _ CONFIRM) (please compare ETSI publication ETS300175-3, 10 months 1992, chapter 7.2.5.3.8). This is connected with the slave C_fChannel direction C_sThe switching of channels is synonymous. The telecommunications interfaces DIFS, DIPS are then connected using a second MWK signal, "CC-CONNECT"(please compare ETSI publication ETS300175-5, 1992, month 10, chapter 6.3.2.7) and a third NWK signal" CC-ConnecT-ACKNOWLEDGE "(please compare ETSI publication ETS 300175-51992, month 10, chapter 6.3.2.7) mutually confirm that the U-plane and the C with the first transmission line number LCNx are established_sA channel. Hitherto, for a channel change of this type, it was necessary to establish two transmission lines.

Fig. 7 shows an additional incentive status chart of how a channel change desired by the second telecommunication interface DIPS (radio transmission/radio reception) can be given to the second telecommunication interface DIFS (radio transmission/radio reception) by controlling the transmission line numbers, and then how this first telecommunication interface DIFS facilitates and carries out the channel change together with the second telecommunication interface DIPS.

Using a second transmission channel C_sFor communication information transmission on the C-plane. In addition to this, the U-plane is utilized. For using a first transmission channel C_fA transmission line with a transmission line number LCN (label) is not yet established. Second transmission channel C_sThan the first transmission channel C_fHas smaller transmission capacity.

Second telecommunication interface DIPS discovery, first transport channel C_fIs necessary. Since for the first transport channel C_fThere is no transmission line with the reference LCN, for example with the reference LCN0, yet, so that the second telecommunications interface DIPS establishes this transmission line.

The selection of the reference LCN, in this case LCN0, as the reference for the transmission line to be set up is not carried out at will, but rather in a targeted manner according to a given selection criterion. This criterion is expressed entirely generally in that reference to each of the possible references LCN0, LCN1, LCN2, the reference being left unused, i.e. empty, for a respective transmission line is taken as the reference LCN.

Instead of the selection criteria described above, it is also possible to refer to specific features of the selection criteria for label issuance. Thus, for example, as in the present case, reference may always be made to the smallest open head reference in each reference LCN0, LCN1, LCN2 or the largest open reference in each reference LCN0, LCN1, LCN 2.

In order to establish a transmission line, a DECT-specific, first B-field signal carrier requesting a BEARER _ REQUEST (please compare ETSI publication ETS300175-3, month 10 1992, chapter 7.3.3.2) is sent to the first telecommunications interface DIFS in accordance with the second telecommunications interface DIPS, which ETSI publication ETS300175-3, month 10 1992, chapter 10.5.1.2 and chapter 10.5.1.3 are preferably responsible for establishing a transmission line, as an instruction (COMMAND).

In this way, the first telecommunications interface DIFS, after receiving the first B-field signal, sends a second B-field signal carrier confirmation BEARER _ CONFIRM (please compare ETSI publication ETS300175-3, month 10 1992, chapter 7.3.3.3) specific to DECT as a RESPONSE (RESPONSE) to the second telecommunications interface DIPS. In this state, i.e. after receiving the second B field signal via the second telecommunications interface DIPS, a further transmission line is established (compare ETST publication ETS300175-3, month 10 1992, chapters 10.5.1.1 to 105.1.3).

This is found by the first telecommunications interface DIFS, so that the first telecommunications interface DIFS sends this first MAC signal "ATTRIBUTES _ T. _ REQUEST" to the second telecommunications interface DIPS (please compare ETSI publication ETS300175-3, month 10 1992, chapter 7.2.5.3.8).

The second telecommunication interface DIPS acknowledges the first MAC signal "ATTRIBUTES _ T. _ REQUEST" by the second telecommunication interface DIPS sending the second MAC signal "ATTRIBUTES _ T. _ CONFIRM" to the first telecommunication interface DIFS. After which the first transport channel C is used_fA communication channel on the C-plane.
